Compared with the non-PCOS group, the mRNA expression levels of GLUT1/LDHA/PFKP were significantly downregulated in the GCs obtained from patients with PCOS (GLUT1: 1.077 ± 0.10 vs. 0.734 ± 0.10; LDHA: 1.005 ± 0.04 vs. 0.641 ± 0.1; PFKP: 1.103 ± 0.08 vs. 0.723 ± 0.10) (Figs. 3A–C). This evidence concerns the gene PFKP and polycystic ovary syndrome.
